[Bots] Line of Sight and Mez optimizations and cleanup (#4746)

* [Bots] Line of Sight and Mez optimizations and cleanup

- Renames `Map:CheckForLoSCheat` to `Map:CheckForDoorLoSCheat` to better reflect what it does.
- Renames `Map:RangeCheckForLoSCheat` to `Map:RangeCheckForDoorLoSCheat` to better reflect what it does.
- Adds the rule `Pets:PetsRequireLoS` to determine whether or not commanded pet attacks require an addition layer of LoS checks for edge-cases.
- Adds the rule `Bots:BotsRequireLoS` to determine whether or not bots require LoS to `^attack`, `^pull` and `^precombat`.
- Adds the rule `Map:ZonesToCheckDoorCheat` to control what if any zones will be checked..
- Corrects, removes and adds LoS checks where necessary.
- Improves door checking logic for locked or triggered doors that could be blocking LoS.
- Cleans up false positives for door cheat checks.
- Adds `drawbox` option to `#door` command. This will spawn points at the center and each corner of the door's "box". It will also spawn points at your and your target's location.
- Improves Mez and AE Mez logic
- Adds more details to the rule `Bots:EpicPetSpellName`

* Remove leftover debugging

* Change return to continue for GetFirstIncomingMobToMez checks

* Move mez chance fail to beginning of cast process
